The authors of an article in Focus magazine, a BBC publication, took a look at statistics in 35 countries to rank those nations according to their tendency towards the seven deadly sins. Australia was found to be the most "sin-prone" nation, with the US coming in second. Canada, Finland, and Spain rounded out the most "sin-prone" rankings.

Topping each of the sin categories were South Korea (lust), the US (gluttony), Mexico (greed), Iceland (sloth and pride), South Africa (wrath) and Australia (envy).

Of course, some question the research methods and the results. http://www.news.com.au/national/australia-ranked-world-number-one-for-sinning/story-e6frfkvr-1225824525361 -via Simply Left Behind

I think this British research team had too much time on its hands, they felt that they might as well take a friendly jab at the Ausies for the fact it used to be a prison colony. That’s my guess, because I don’t think there actually is a person that would pay for these pointless statistics. But, there are links between giving into vices and guilt, so it's comparable to the religiosity in Australian culture.
